The display unit 40 may be formed in a touch screen shape that may input or change information of the setup factors through a touch based on a finger of the user.

Therefore, the user may input or change the setup factors such as washing strength ‘m’, the number of rinsing times ‘n’, dehydrating strength ‘o’, and water temperature ‘p’. through the display unit 40. For example, the plurality of courses a to 1 provided in the main course selection unit 30 have setup factors previously set in accordance with the respective courses. That is, the setup factors such as washing strength ‘m’, the number of rinsing times ‘n’, dehydrating strength ‘o’, and water temperature ‘p’ are previously determined in each course.

Hereinafter, the setup factors which are previously determined in accordance with each course will be referred to as “standard setup factors”. Therefore, if the user selects a desired course from the main course selection unit 30, the setup factors (that is, standard setup factors) corresponding to the selected course may be displayed on the display unit 40. At this time, the user may drive the clothes treating device 1 in accordance with the standard setup factors by directly inputting an execution command to the execution input unit 33 or drive the clothes treating device 1 by inputting the execution command to the execution input unit 33 after changing the setup factors displayed on the display unit 40.

The control unit 800 may store information on the concentration of the detergent, which is received from the detergent concentration sensor 150, in a memory 830, which will be described later.

Meanwhile, the clothes treating system according to the present invention includes the external terminal 2 and the clothes treating device 1 formed to perform communication with the external terminal 2. Features related to communication between the external terminal 2 and the clothes treating device 1 will be described in detail with reference to FIG. 4.

FIG. 4 is a block diagram briefly illustrating a communication relation among a control unit of a clothes treating device, an external terminal and an external server. Referring to FIGS. 2 and 4, the control unit 800 provided in the clothes treating device 1 may include a controller 810 for controlling the course selection unit 30 and the display unit 40, a light emitting unit (or light emitter) 820 for sequentially or selectively lighting the indicator lights 35 displayed on the course selection unit 30, and a memory 830 for storing the information input through the course selection unit 30 and the display unit 40.

Also, the control unit 800 may be formed to perform communication with the external terminal 2. To this end, the control unit 800 and the external terminal 2 may respectively include communication modules 840 and 3. At this time, the control unit 800 and the external terminal 2 may be formed to perform NFC communication, and the communication module 840 of the control unit 800 and the communication module 3 of the external terminal 2 may be NFC modules, respectively. That is, each of the clothes treating device 1 and the external terminal 2 may include an NFC module for NFC communication.

The controller 810 receives information input to the course selection unit 30 and the display unit 40 by the user, and drives the respective elements of the clothes treating device 1 in accordance with the received information and at the same time transfers the corresponding information to the memory 830. Therefore, the information such as the number of selection times of the course selected through the course selection unit 30 and the number of input times of the setup factors input to the display unit 40 may be stored in the memory 830.

Also, the controller 810 may control the light emitting unit 820 to sequentially or selectively light the indicator lights 35 corresponding to the plurality of courses a to 1 displayed on the course selection unit 30. The user may select one of the plurality of courses a to 1 displayed on the course selection unit 30 by manipulating (i.e., rotating) the manipulation unit 32. At this time, the indicator lights 35 may be lighted sequentially in accordance with rotation of the manipulation unit 32.

For example, if the power source is input to the clothes treating device 1, the indicator light 35 provided at the position corresponding to the first course ‘a’ of the plurality of courses a to 1 provided in the course selection unit 30 may be lighted. At this time, if the user rotates the manipulation unit 32 at a predetermined angle clockwise or counterclockwise, the indicator light 35 provided at the position corresponding to another course ‘b’ or ‘1’ adjacent to the first course ‘a’ clockwise or counterclockwise may be lighted.

Meanwhile, the external terminal 2 may be formed to display information on an external environment and at least one or more recommended courses previously set according to the information of the external environment. For example, after the power source is input to the clothes treating device, and before the execution command is input through the execution input unit 33, the external terminal 2 may be formed to display information on an external environment and at least one or more recommended courses previously set according to the information of the external environment.

Preferably, before the course selection unit 30 is manipulated by the user, the external terminal 2 may be formed to display information on an external environment and at least one or more recommended courses previously set according to the information of the external environment. At this time, the holder unit 50 included in the clothes treating device 1 may be provided with a sensor 60 electrically connected to the power input unit 31. Therefore, if the external terminal 2 is held in the holder unit 50, the sensor 60 may be formed to turn ON the power source of the clothes treating device 1. That is, even though the power input unit 31 of the clothes treating device is not manipulated, if the external terminal 2 is held in the holder unit 50, the sensor 60 may be formed such that the power source of the clothes treating device 1 is turned ON.

That is, the power source of the clothes treating device 1 may be input through the power input unit 31 provided in the course selection unit 30 or holding of the external terminal 2 in the holder unit 50. Also, the power source of the clothes treating device 1 may be input through NFC communication between the clothes treating device 1 and the external terminal 2. That is, if the clothes treating device and the external terminal 2 are within a predetermined distance in a state that they can perform NFC communication, the power source of the clothes treating device 1 may be formed to be turned ON.

The external terminal 2 may include a display unit 4, and information related to the operation of the clothes treating device 1 may be displayed on the display unit 4. Also, the controller 810 is formed to receive information related to the concentration of the detergent contained in the washing water or the rinsing water inside the clothes treating device 1 from the detergent concentration sensor 150. For example, a washing course is performed several times, the detergent concentration sensor 150 may be formed to sense the concentration of the detergent contained in the washing water during the washing course performed finally. Likewise, when a rinsing course is performed several times, the detergent concentration sensor 150 may be formed to sense the concentration of the detergent contained in the rinsing water during the rinsing course performed finally.

At this time, the concentration of the detergent sensed by the detergent concentration sensor 150 may be stored in the memory 830. For example, a date when the clothes treating device 1 is driven and the concentration of the detergent sensed in the washing water and the rinsing water at the date may be stored together in the memory 830.

That is, the date when the clothes treating device 1 is driven and the concentration of the detergent sensed in the washing water and the rinsing water at the date may be stored in the memory 830. Meanwhile, if the clothes treating device 1 is driven several times at the same date, the date when the clothes treating device 1 is driven and the concentration of the detergent sensed in the washing water and the rinsing water at the corresponding date and time may be stored in the memory 830. Hereinafter, various embodiments of the information displayed on the display unit 4 of the external terminal 2 will be described.

The display unit 4 of the external terminal 2 may be formed in a touch screen shape that enables a touch input.

Therefore, the user may touch one or more recommended courses displayed on the display unit 4, and may drive the clothes treating device 1 through an input of the execution command through the execution input unit 33 provided in the clothes treating device 1. Of course, the clothes treating device 1 may be driven through a touch of an execution icon displayed on the display unit 4.

That is, the user may select a desired course through the external terminal 2 even without manipulating the course selection unit 30 provided in the clothes treating device 1. Meanwhile, the clothes treating system according to the present invention may further include an external server 9 storing data of the information on the external environment and data of at least one or more recommended courses previously set according to the external environment.

At this time, the external server 9 may be formed to update the data of the information on the external environment in real time. And, the external terminal 2 may be formed to enable Wi-Fi communication with the external server 9, and the data of the information on the external environment, which are updated by the external server 9 may be transmitted to the external terminal 2. For this Wi-Fi communication, each of the external terminal 2 and the external server 9 may include a Wi-Fi module (not shown).

That is, the external terminal 2 may be formed to receive the data of the information on the external environment and the data on one or more recommended courses previously set based on the external environment from the external server 9. At this time, data transmission from the external server 9 to the external terminal 2 may be performed in real time or time interval which is previously set.

Meanwhile, after the execution command is input through the execution input unit 33 of the clothes treating device 1, the external terminal 2 may be formed to display information on the operation state of the clothes treating device 1 in real time. In this case, the information on the operation state may include name of a course which is performed, the number of remaining rinsing times, dehydrating strength, information as to whether a steam course is performed, information as to whether a drying course is performed, and remaining washing time (that is, washing end time).

Therefore, even though the element such as the display unit 40 is not provided in the clothes treating device 1, the user may acquire the information on the operation state of the clothes treating device 1 through the external terminal 2 which performs communication with the clothes treating device 1. That is, the display unit 40 of the clothes treating device 1 may be replaced with the external terminal 2. Hereinafter, the information of the recommended course displayed on the display unit 4 of the external terminal 2 will be described exemplarily.

For example, the external terminal 2 may further include a memory module 6 and a control module 5. Information on a previously set washing period of the tub 100 or the drum and information on the number of driving times of the clothes treating device, which is previously set, may be stored in the memory module 6.

Therefore, if the external terminal 2 receives the information on the washing timing of the tub 100 or the drum 200, which is most recently performed, from the clothes treating device 1, the control module 5 determines whether a period from the washing timing to a current time exceeds the previously set washing period stored in the memory module 6. If the control module 5 determines that the period from the washing timing to the current time exceeds the previously set washing period stored in the memory module 6, the control module 5 displays a text (for example, “tub washing required” or “drum washing required”) of the need of washing of the tub 100 or the drum 200 on the display unit 4.

At this time, the previously set washing period may previously be set to 30 days, 50 days or 100 days. Also, if the external terminal 2 receives the information on the number of driving times of the clothes treating device 1, which is performed until now, from the clothes treating device 1, the control module 5 compares the number of driving times with the number of previously set driving times stored in the memory module 6. And, the control module 5 controls the display unit 4 to display whether the number of driving times of the clothes treating device 1 is close to the number of previously set driving times stored in the memory module 6, on the display unit 4.

At this time, the number of previously set driving times may previously be set to 10 times, 30 times or 50 times. Also, after the tub 100 or the drum 200 is washed, the number of driving times of the clothes treating device 1 is again counted from the beginning (that is, from 1). By the aforementioned configuration, the user may determine whether to perform washing of the tub or the drum before washing the clothes, on the basis of the information displayed on the display unit 4 of the external terminal 2.

Therefore, if the external terminal 2 receives the information on the washing timing of the tub 100 or the drum 200, which is most recently performed, from the clothes treating device 1, the control module 5 determines whether a period from the washing timing to a current time exceeds the previously set washing period stored in the memory module 6. If the control module 5 determines that the period from the washing timing to the current time exceeds the previously set washing period stored in the memory module 6, the control module 5 displays a text (for example, “tub washing required” or “drum washing required”) of the need of washing of the tub 100 or the drum 200 on the display unit 4. At this time, the previously set washing period may previously be set to 30 days, 50 days or 100 days.

Also, if the external terminal 2 receives the information on the number of driving times of the clothes treating device 1, which is performed until now, from the clothes treating device 1, the control module 5 compares the number of driving times with the number of previously set driving times stored in the memory module 6. And, the control module 5 controls the display unit 4 to display whether the number of driving times of the clothes treating device 1 is close to the number of previously set driving times stored in the memory module 6, on the display unit 4.

At this time, the number of previously set driving times may previously be set to 10 times, 30 times or 50 times. Also, after the tub 100 or the drum 200 is washed, the number of driving times of the clothes treating device 1 is again counted from the beginning (that is, from 1). By the aforementioned configuration, the user may easily determine whether to perform washing of the tub or the drum before the specific course is executed through the clothes treating device (that is, before washing the clothes), on the basis of the information displayed on the display unit 4 of the external terminal 2.

Also, according to the control method of the clothes treating system according to the present invention, a manual text which describes a use method of the clothes treating device and function and effect according to each course may be replaced simply by the external terminal. Also, if the user manipulates the clothes treating device in a state that the external terminal 2 is held in the holder unit 50 of the clothes treating device 1, information on function and effect per course or setup factor of the clothes treating device 1 may easily be provided from the external terminal 2 in real time.
